Terms of Service

Last updated: 18 May 2026

These terms govern your use of Saavu, a wellness app for sauna and cold plunge sessions. They include important medical and safety notices. Please read them carefully before using the app.

1. The agreement

These Terms of Service ("Terms") form a legal agreement between you and Saavu ("Saavu", "we", "our", "us"). By installing, signing into, or otherwise using the Saavu app or saavu.app website, you accept these Terms. If you do not accept them, do not use Saavu.

2. Eligibility & age

• You must be at least 16 years old to create a Saavu account.
• If you are between 16 and 18, you should use Saavu only with a parent or guardian's awareness and consent, and only after a doctor has cleared you for sauna and cold-water exposure.
• Saavu is rated 17+ on the App Store because heat exposure and cold immersion carry adult-level physiological risks.

3. Your account

• You are responsible for keeping your login credentials confidential and for all activity on your account.
• You agree to give accurate information when signing up and to keep it up to date.
• You may not transfer your account to anyone else.
• Notify us promptly at hello@saavu.app if you believe someone has accessed your account without permission.

4. Licence to use the app

Subject to these Terms, Saavu grants you a limited, personal, non-exclusive, non-transferable, revocable licence to install and use the Saavu app on devices you own or control, for your own personal, non-commercial use.

You may not (a) copy, modify, or create derivative works of the app; (b) reverse engineer, decompile, or disassemble the app except to the extent permitted by applicable law; (c) rent, lease, sublicense, sell, or otherwise commercialise the app; or (d) remove or alter any copyright or proprietary notices.

5. Subscriptions, billing & renewal

Saavu offers a free tier and paid Saavu Pro plans.

• Free tier: core session tracking, face states, last 10 sessions, venue finder, basic insights.
• Pro monthly: £4.99 / month (or local equivalent shown on the App Store).
• Pro yearly: £39.99 / year (or local equivalent), a saving of about a third compared with paying monthly.
• Trial: a 7-day free trial is available to first-time Pro subscribers. If you do not cancel before the trial ends, the subscription will start and your account will be charged.

Auto-renewal disclosure (required by Apple)

• Payment will be charged to your Apple ID account at confirmation of purchase.
• Your subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period.
• Your account will be charged for renewal within 24 hours prior to the end of the current period, at the price shown for the chosen plan.
• You can manage your subscription and turn off auto-renew by going to your account settings on the App Store after purchase.
• Any unused portion of a free trial, if offered, will be forfeited when you purchase a subscription.

6. Cancellation & refunds

You can cancel your subscription at any time through the App Store (iOS: Settings → [your name] → Subscriptions → Saavu) or Google Play. Cancellation takes effect at the end of the current billing period; you retain Pro access until then.

Refund requests are handled by Apple or Google according to their policies. Saavu cannot directly issue refunds for App Store or Play Store transactions. To request a refund, use Apple's "Report a Problem" page (reportaproblem.apple.com) or Google Play's purchase history.

EU/UK consumers: by purchasing a Pro subscription and downloading content immediately, you acknowledge that any 14-day right of withdrawal under the Consumer Rights Directive ends when use begins. Where law requires it, your statutory rights are unaffected.

7. Health and safety warnings

Sauna and cold-water exposure carry real physiological risk. Saavu's safety features (heart-rate ceiling alert, hydration nudge, voice cues) are aids, not guarantees. You are responsible for your own safety. In particular:

• Do not use Saavu sessions if you have uncontrolled hypertension, recent cardiac events, unstable angina, severe aortic stenosis, or any condition for which heat or cold exposure has been contraindicated by your doctor.
• Do not use cold plunge sessions if you are pregnant, immediately post-surgery, or have peripheral vascular disease, Raynaud's, or cold urticaria, unless explicitly cleared by your doctor.
• Hydrate before and after sessions. Never use sauna or cold plunge while intoxicated or after taking medications that impair thermoregulation.
• Never use a cold plunge alone in deep water. Cold-shock response can cause involuntary gasping that leads to drowning.
• Get out of the sauna or the cold immediately if you feel light-headed, nauseous, chest pain, palpitations, sharp peripheral pain, or any unfamiliar sensation. Seek medical help if symptoms persist.

8. User content & venues

• You may submit venue suggestions, venue photos, reviews, and free-text reflection notes. We refer to this as "User Content".
• You retain ownership of your User Content. By submitting it you grant Saavu a worldwide, royalty-free, non-exclusive licence to host, display, and distribute it within Saavu, for the sole purpose of running the service.
• You represent that you have the right to submit each piece of User Content and that it does not infringe anyone's rights or violate any law.
• Venue submissions and photos are moderated before publication. We may decline, edit, or remove User Content that breaches these Terms or our community guidelines.
• Your private session data and reflection notes are not User Content for purposes of this licence. They remain private unless you explicitly share them.

9. Third-party wearables

Saavu can connect to Whoop, Oura, Garmin, and Polar via each provider's official OAuth flow. Those services are operated by third parties. Their availability, data accuracy, and continued integration are outside our control. Disconnecting a provider does not remove sessions already imported.

10. Prohibited conduct

• Submitting false venue information, harassing other users, or impersonating anyone.
• Attempting to bypass safety features (HR ceiling, hydration nudge) for any commercial product claim.
• Attempting to access another user's data or our systems without authorisation.
• Using Saavu to operate a commercial sauna or recovery business without our prior written consent.
• Scraping the app or website, or running automated processes against our APIs.

11. Termination

You may delete your account at any time via Settings → Account → Delete Account. We may suspend or terminate your access if you materially breach these Terms or if continued service would expose us to legal risk. We will give reasonable notice where lawful and where the breach is curable.

12. Disclaimer of warranties

Saavu is provided "as is" and "as available". To the maximum extent permitted by law, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the app will be error-free, uninterrupted, or that any particular health outcome will follow from using it.

13. Limitation of liability

To the maximum extent permitted by law, Saavu's total liability arising out of or related to these Terms or your use of the app is limited to the greater of (a) £100 or (b) the amount you have paid Saavu in the 12 months preceding the claim.

Saavu will not be liable for any indirect, incidental, special, consequential, or exemplary damages, including loss of data, loss of profit, or loss of goodwill, or for any personal injury arising from your use of saunas, cold plunges, or any other physical activity informed by the app.

Nothing in these Terms limits liability that cannot lawfully be limited, including liability for death or personal injury caused by our negligence, or for fraud.

14. Indemnification

You agree to defend, indemnify, and hold Saavu and its officers harmless from any third-party claim arising out of (a) your breach of these Terms, (b) your User Content, or (c) your misuse of the app, except to the extent caused by our own breach.

15. Disputes & governing law

These Terms are governed by the laws of England and Wales, without regard to conflict-of-laws principles. The courts of England and Wales have exclusive jurisdiction. If you are a consumer resident in the EU, you retain the protection of mandatory consumer-law provisions of the country in which you live, and you may bring proceedings in your local court.

16. Copyright complaints

If you believe content on Saavu infringes your copyright, send a written notice to hello@saavu.app with: (a) your contact details and a physical or electronic signature; (b) identification of the copyrighted work; (c) identification of the infringing material and its location in Saavu; (d) a good-faith statement that you believe the use is not authorised; and (e) a statement under penalty of perjury that the notice is accurate and that you are authorised to act for the rights holder. We will respond promptly and may remove or disable access to the material.

17. General provisions

• Severability. If any provision is found unenforceable, the rest remain in force.
• No waiver. Our failure to enforce a right does not waive it.
• Assignment. You may not assign these Terms; we may assign them in connection with a merger, acquisition, or sale of assets.
• Force majeure. Neither party is liable for failure caused by events beyond reasonable control (e.g. major outages, natural disasters).
• Entire agreement. These Terms, the Privacy Policy, and any in-app disclosures form the entire agreement between you and Saavu.
• Changes. We may update these Terms; material changes will be notified in-app or by email at least 14 days before they take effect.

18. Apple-specific end-user terms

The following terms apply when you download Saavu from the Apple App Store:

• These Terms are between you and Saavu only, not with Apple. Apple is not responsible for the app or its contents.
• Apple has no obligation to provide any maintenance and support services for the app.
• If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any). To the maximum extent permitted by law, Apple has no other warranty obligation.
• Saavu (not Apple) is responsible for addressing any claims relating to the app or your possession or use of it, including product liability, regulatory compliance, and consumer protection claims.
• Saavu is responsible for any third-party intellectual-property infringement claim regarding the app.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you as a user.
• You confirm you are not in a U.S.-embargoed country and are not on any U.S. government list of prohibited or restricted parties.
